(01. 2ll-56A-) 12 Claims.

The present invention relates to metal sash and store front constructions and has for its primary object the provision of novel and improved means for mounting and retaining a pane of glass in proper adjusted position.

Another object of the invention is the provision of a sash or store front construction embodying inner and outer glass retaining sections of improved construction and arrangement associated with one another in a novel manner and having novel means for connecting the said sections together to firmly clamp the pane of glass in position therebetween.

Another object of the invention is the provision of a sash or store front construction of maximum simplicity, ease of assembly and operation, and embodying clip members or the like associated with the outer section and actuated by adjusting means associated with the inner section to effect the securing of the pane of glass in place.

A further object of the invention is the provision of improved tensioning means embodying a plurality of cooperating clip members and adjusting members, together with positive means for preventing further tightening of said adjusting members when said clip members have caused the sash sections to exert a substantially predetermined clamping pressure upon the glass.

'A still further object of the invention is the provision of improved tensioning means for connecting the stationary and movable sash sections together in such a manner that they will exert a resilient cushioned pressure upon the pane of glass while at the same time permitting relative movement between the said sections to take care of vibration and expansion and contraction of the glass and metal sash construction without disturbing the setting of the glass or causing. injury thereto.

Other objects and advantages of the invention will become more apparent during the course of the following description, when taken in connection with the accompanying drawing.

In the drawing, wherein like numerals are employed to designate like parts throughout the same:

Fig. 1 is a front elevation illustrating a store front embodying the present invention; and

Fig. 2 is a vertical transverse sectional View through the metal sash construction provided by the invention.

In Fig. l of the drawing, the numeral 5 designates in its entirety a glazed opening in which is mounted a sheet or pane of glass 6 supported in the window opening by the metal sash conill struction 1 arranged at the top, bottom, and sides of said window. The front wall of the building may, if desired, be faced with stone, Vitrolite, or other ornamental slabs or panels 8-.

With reference particularly to Fig. 2, the metal sash construction is mounted upon a wooden sill 9 in front of a wooden back stop 10 which is carried by said sill. The sash construction comprises a stationary rear section I I and a movable front section l2 pivotally associated with one another to clamp the pane of glass 6 in position therebetween. The rear section H comprises a vertical back wall [3 which abuts the wooden back stop' l0 and is secured thereto by wood screws or the like 14. Formed integral with the back wall l3, adjacent its upper end, is an inwardly directed gutter portion l5 terminating in a substantially vertical lip l6 engaging the inner face of the pane of glass 6. The back wall I3 is provided at its lower end with a forwardly directed ledge l'l terminating at its outer end in a depending web portion I8. Formed integral with the web portion I8 is a rearwardly directed wedge portion l9 cooperating with said ledge portion I! to provide a rearwardly facing horizontal channel 29. Extending forwardly from the web portion l8 isthe horizontal base plate 2| supported upon the sill 9 and secured thereto by screws or the like 22. The base plate 2! is provided at its outer end with an upstanding longitudinally extending front part or flange 23 having the outer and inner arcuately curved concave and convex surfaces 24 and 25 respectively.

The base plate 2| does not contact directly with the wooden sill 9 but instead preferably rests upon a horizontal metal sill plate 26 covering the upper surface of the wooden sill and being also secured thereto by the screws 22. The sill plate 26 may be provided at its outer end with a downturned flange 2T overlapping the outer marginal portions of the adjacent facing panels 8, and at its opposite end with a vertical upstanding leg 28. Formed at the upper end of the leg 28 is a forwardly directed wedge portion 29 snugly received within the channel 20 in the rear section II, The cooperating wedge portions 19 and 29 form a seal for preventing the seepage of water and moisture between the metal sash construction and the wooden sill and back stop thereby maintaining the said sill and back stop perfectly dry and eliminating dry rot, deterioration, and warpage.

The front section l2 comprises a face piece 30 having the desired profile and provided at its pper end with a 11p 31 en ging the outer face of the pane of glass 6. The face piece 33 is formed at its lower end with a longitudinally extending rib 32 having an inner arcuately curved convex surface 33 adapted to engage the front concave surface 24 of upstanding flange 23 to provide a so-called knuckle-joint. The curved front surface 24 of the flange 23 constitutes a seat or bearing upon which the outer section is adapted to fulcrum to clamp the pane of glass 6 between the lip 3| thereof and the lip [6 of the rear section II v The means for rocking the front section I2 on said knuckle-joint to tension said section against the pane of glass comprises clip members34 associated with the front section and actuated by adjusting screws 35 threaded through the gutter portion l5 of the rear section. Any desired number of clip members 34 may be provided and each comprises a rigid body portion 36 formed with the oppositely directed substantially vertical ears .311'and 38. A channel 33 is formed upon the rear face of the front section l2 by the inturned flanges 40 and 4!, and received within said channel behind the flanges 40 and 4| are the ears 31. and 38'respectively of'the body portion 36. The body portion 36 of the clip member is formed at its lower end-with an arcuately curved concave surface- 42 adapted to engage the inner convex surface 25 of the upstanding flange 23 when said clip member is actuated by the adjusting screw 35.

Carried by'the rigid body portion 36 of the clipv member is a rearwardly extending substantially=horizontal lever arm 43 comprising a spring portion 44 and a rigid plate element 45 carried by said spring portion. The spring portion is bent at its outer end as at 46 and secured within a recess 41 in the body portion 36 of the clip member. The opposite or inner end of the spring portion is similarly bent as at 48 and is secured within a recess 49 in the rigid plate element 45. The plate element 45 is engageable by the adjusting screw 35 threaded through the gutter portion l5 of rear section I I. The plate element 45 is also provided with a substantially horizontal lug 50 which is adapted to engage the horizontal ledge ll of the rear section upon flexingof the spring portion 44. The ledge l1 therefore serves as a positive stop to prevent excessivetightening of the adjusting screw 35. 1

When installing a light of glass in an opening to be glazed, the metal sill plate 26 is first properly positioned upon the wooden sill 9 and the rear sash section II associated therewith and secured by the screws 22 and 14 to the wooden sill 9 and back stop l respectively. The pane of glass 6is then set in place and supported at its lower edge upon a plurality of setting blocks SI of any desired construction and which are arranged at spaced intervals longitudinally of the horizontal 'base plate 2! of the rear section. After the glass has been positioned upon the setting blocks with the rear surface thereof in contact with'the lip I 6' of rear section II, the movable front section I2 is properly associated with said rear section. This is done by bringing the rib 32 at the bottom of the front section into engagement with theupstanding flange 23 and thel ip 3-l'at" the upper end thereof in contact with the outer face of the pane of glass. When so positioned, the lower portions of the clip members 34 will be disposed inwardly of the upstanding flange 23, with the curved surfaces 42 of said clip members being closely adjacent the curved rear surface 25 of said flange. The lever arms 43 of the clip members will extend rearwardly toward the fixed section beyond the edge of the glass pane.

The adjusting screws are then tightened to engage the rigid plate elements of the lever arms and downward pressure thereon will cause the flexing of the spring portions 44, as indicated by the broken lines in Fig. 2], whereby to urge the lip 3| of the movable front section into yielding engagement with the glass. This action will also bring the curved surfaces 42 of the clip members into engagement with the curved rear surface 25 of flange 23.

In this way, the movable front section will be maintained in firm clamping engagement with the pane of glass 6 to effectively secure the same in place. On the other hand, the spring portions 44 of the lever arms 43 will provide for a certain amount of flexibility and resiliency to take care traction of the glass and metal sash construction without'disturbing the setting of the pane or causing injury thereto. Likewise, the liability of breakage of the glass under severewind strain and other shocks to which it may be subjected in use will be greatly reduced.

The adjusting screws 35 are adapted to be tightened until the lugs 56 engage the horizontal ledge I l whereupon further tightening of the said screws will be prevented. The lugs therefore cooperate with the ledge I! to limit movement of the rigid plate elements 45 and prevent over-tightening of the adjusting screws 35. In

this way, the application of excessive clamping pressure upon the glass, such as might result in the breakage thereof, is effectively prevented.

It is to be understood that the form of the invention herewith shown and described is to be taken as the preferred embodiment of the same, and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
